Oracle Linux 3 / 4 : perl (ELSA-2010-0457)

high Nessus Plugin ID 68047

Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

From Red Hat Security Advisory 2010:0457 :

Updated perl packages that fix two security issues are now available for Red Hat Enterprise Linux 3 and 4.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Perl is a high-level programming language commonly used for system administration utilities and web programming. The Safe extension module allows users to compile and execute Perl code in restricted compartments.

The Safe module did not properly restrict the code of implicitly called methods (such as DESTROY and AUTOLOAD) on implicitly blessed objects returned as a result of unsafe code evaluation. These methods could have been executed unrestricted by Safe when such objects were accessed or destroyed. A specially crafted Perl script executed inside of a Safe compartment could use this flaw to bypass intended Safe module restrictions. (CVE-2010-1168)

The Safe module did not properly restrict code compiled in a Safe compartment and executed out of the compartment via a subroutine reference returned as a result of unsafe code evaluation. A specially crafted Perl script executed inside of a Safe compartment could use this flaw to bypass intended Safe module restrictions, if the returned subroutine reference was called from outside of the compartment.
(CVE-2010-1447)

Red Hat would like to thank Tim Bunce for responsibly reporting the CVE-2010-1168 and CVE-2010-1447 issues. Upstream acknowledges Nick Cleaton as the original reporter of CVE-2010-1168, and Tim Bunce and Rafael Garcia-Suarez as the original reporters of CVE-2010-1447.

These packages upgrade the Safe extension module to version 2.27.
Refer to the Safe module's Changes file, linked to in the References, for a full list of changes.

Users of perl are advised to upgrade to these updated packages, which correct these issues. All applications using the Safe extension module must be restarted for this update to take effect.

Solution

Update the affected perl packages.
